Do you know if it's OK to use canned fruit and vegetables to make purees for a 5/6 month old baby if there is no salt or sugar added? I know I should watch out for sodium/syrup and only use fruit/vegetables packed in water, but do you know if it's OK to make purees out of them? And can those purees be then frozen? The reason I'm asking is that my book on weaning suggests peaches and mangoes for fruit purees which obviously won't be available fresh this autumn. Also am wondering if using canned vegetables/fruit could save time as they're already peeled and cooked. Thanks in advance!
